Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a release agent for food casings.

More specifically, the present invention relates to a release agent applied to skinless cellulose casings and the like.

[Conventional technology]

Among processed foods, small-sized sausages such as Wiener sausages and 7-Rank Full Sausages are manufactured by using meat emulsions made from animal intestines, regenerated cellulose or other cellulose derivatives, alginates, collagen, etc. during the processing process. After filling the artificial casing, it is subjected to processes such as smoking and shoeing.

There are two types of finished products: those that are supplied to the market as they are, and those that have the casing removed and are supplied with only processed food content.The latter is a skinless sausage. It is a product that has been developed in recent years for the purpose of mass production using mechanization. The main machines used to manufacture this product are a high-speed automatic filling machine and a peeling machine, but the casing used must also be adaptable to these machines.

Specifically, in the production of small-sized sausages,
First, raw meat such as pork or beef is ground, and seasonings are added to this.
Spices and other ingredients are added and kneaded, and the meat emulsion thus prepared is filled into a casing using a stuffer and shaped into a predetermined size. The machine used for this purpose is a high-speed automatic filling machine, for which the casing is usually packed with tubular materials approximately 17 to 48 m long and compressed to approximately 20 to 40 cm ( Snacks or strands). The mechanical suitability of this snack in the filling process requires that the snack exhibits predetermined properties such as inner diameter, straightness, self-retention, release of pleats, lubricity on the inner and outer surfaces, and strength.

After filling, the semi-finished product is subjected to processing such as drying, smoking, and shoeing according to the technology in the industry, and after cooling,
An operation is carried out to remove the casing from the meat content. The machine used for this work is a peeling machine,
The top surface of the sausage links running at high speed is torn apart in the direction of flow with a sharp knife, and the torn casings are separated with compressed air and either rolled downwards or sucked into a vacuum chamber. In this case, the delicate state of adhesion between the meat and the casing determines whether or not the work can be carried out smoothly. It gets stuck and completely disrupts the smooth flow of work.

This peelability is affected by the raw meat used and the content of additives, as well as the manufacturing conditions of the processing process.
'1. Therefore, sausage manufacturers select all the conditions to satisfy the releasability as much as possible while taking into account the characteristics of other products. However, with modern high-speed machines, it is not possible to perform a smooth peeling operation by simply setting these manufacturing conditions, and the inner surface of the casing must be actively treated to promote femininity. This has led to improved workability.

Various stripping agents have been proposed for this purpose, and a stripping agent containing water-soluble cellulose ether as a single component, which has particularly good performance, is generally used. When used with a treatment agent, there is a problem of sticking of the treated casing pleats together. If this adhesion force is large, tearing occurs due to partial adhesion during deshering (releasing the fillet), which seriously impedes the filling operation. Therefore, it is essential to add an anti-sticking agent to the release agent.

Various anti-sticking agents have been proposed in the past as this type of anti-sticking agent.
Examples include animal oils, vegetable oils, mineral oils, silicone M, water ii fatty acid partial ester adducts (Japanese Patent Publication No. 53-20578), monoglyceride-diglyceride mixtures of oleic acid (Japanese Patent Publication No. 53-20578), −
63962), partial fatty acid ester of polyhydric alcohol (JP 54-70466), sucrose fatty acid ester (JP 55-7066), wax (JP 59-98646) , phosphorus jJR (Unexamined Japanese Patent Publication No. 5
9-55141), but most of these anti-sticking agents are water-soluble and have low anti-sticking ability, and water-insoluble ones must be made into aqueous dispersions. Not only is the operation complicated, but the dispersion stability and viscosity of the prepared aqueous dispersion often pose major practical constraints.

[Problem that the invention seeks to solve]

The present invention aims to provide a release agent using an anti-adhesion agent that does not have such problems, and while using a water-soluble agent as an anti-adhesion agent, it is not absorbed into the cellulose film and remains on the surface of the film. As a result of various studies in search of a product that would still exhibit excellent anti-sticking properties, it was discovered that an ethylene oxide-propylene oxide copolymer can effectively solve the above problem.

[Means for Solving the Problems] and [Operation] Accordingly, the present invention relates to a release agent for food casings, and this release agent for food casings comprises a water-soluble cellulose ether, an ethylene oxide-propylene oxide copolymer, and a polyol. It consists of an aqueous solution of.

The water-soluble cellulose ether is preferably carboxymethylcellulose (OMO), which passes the standards of the Japan Food Additives Standard for food use, and has a carboxymethyl group of about 0.0% per anhydroglucose unit of cellulose.
4 to 2.0, and the viscosity of a 2% aqueous solution of it is about 10 to 5Q.
cps0 is preferably used.

The ethylene oxide-propylene oxide copolymer is a block copolymer or random copolymer thereof, preferably a block copolymer having an ethylene oxide content of about 20 to 80% by weight, and a molecular weight of about 1900 to about 1,900. 6500 and water-soluble are used. Examples of the polyol used include glycerin, propylene glycol, triethylene glycol, polyethylene glycol, and sorbitol.

The concentration of each of these components that forms the entire aqueous release agent solution is not necessarily constant depending on the type of casing being treated, treatment conditions, etc.; About 5-25% ethylene oxide-propylene oxide copolymer, preferably about 10-25%
20%, about 20-80% polyol, and the remainder water.

Apply this amount to the casing (casing l cn
From the point of view of water-soluble cellulose ether (per liter), water-soluble cellulose ether is 0.0
015~0.015 m? , preferably 0.003 to 0
．． 010~, and if the coating amount is less than this, the stripping property will be substantially insufficient.On the other hand, if the coating amount is more than this, the viscosity of the stripping agent aqueous solution will become high, which will not only cause problems in operation. , adhesion force (the force required to release the folds of the stick when the tied end of the stick is gripped by a fixed tension gauge and the stick is pulled downward at a constant speed of 30 crn/min) becomes large and becomes a cause of inhibiting filling suitability.

As mentioned above, the ethylene oxide-propylene oxide copolymer is used to completely prevent the casing from sticking due to water-soluble cellulose ether.
), the coating amount is preferably 0.058 to 0.116. If the amount applied per casing l crd is less than this, the anti-sticking effect will not be sufficiently exhibited and the casing may be damaged during filling. On the other hand, if a larger amount is used, the adhesion force will become too small,
The stick will break easily.

The polyol is used to control the total amount of water added to the stick; the water acts as a solvent for the water-soluble cellulose, and also provides flexibility to the casing to give the stick the proper adhesion properties. Effective in increasing self-retention.

The release agent can be applied to the casing by injecting it into the casing just before the dryer, removing the excess amount and drying it (slagging method), or by passing it through a mandrel during shearing to coat the inner surface of the casing. A method of spraying the agent (spraying method), a method of mixing a stripping agent in the final wet tank and letting it penetrate from the outside of the casing to reach the inner surface (infiltration method), A method is used in which the release agent is completely added to the stock solution and molded (Visconis mixing method).

〔Effect of the invention〕

When applied to an aqueous release agent casing according to the present invention, particularly to a hirulose casing, it not only fully exhibits its anti-sticking properties, but also prevents folds from folding due to the lubricating properties of the ethylene oxide-propylene oxide copolymer. It is also possible to reduce the friction caused by the pleating shaft of the machine, making it possible to fully satisfy both quality and operability.

〔Example〕

Next, the present invention will be explained with reference to examples.

EXAMPLE The following release agent was sprayed onto the inner surface of a tubular cellulose casing with a diameter of 16 um, which was MAMed by the viscose method, through the mandrel of a shredder, at a rate of 0.00 mm per crl of the casing.
It was applied at a ratio of 58 to 58%.

a, 25°C] Stripping agent A was added to 3% ethylene oxide-propylene oxide copolymer, and 6% propylene glycol was added.
They were each changed to 6%.

[Stripping agent C; viscosity 275 cps, 25°C] Stripping agent A, ethylene oxide-propylene oxide copolymer 30%
and 39% propylene glycol.

The conditions during the lathering operation and the quality of the obtained stick samples using each of the above-mentioned release agents were as follows.

(When stripping agent A'f was used) There was no abnormality in the pleating operation, and the operation was performed normally. Also, the adhesion strength of the finished stick is 15
0 to 180, and appropriate pleat release properties were obtained.

(When removing agent B is used) When shirring, the lubricity with the shirring mandrel is insufficient, causing a delay in the forwarding of the folded casing, resulting in damage to the casing due to the shirring gear. In addition, the adhesion force of the finished stick was as high as 300 to 350, and when the sausage was being filled, tears occurred due to close contact between the folds when releasing the folds, making it impossible to obtain a satisfactory filling operation. .

(Striping agent of: When used) The viscosity of the stripping agent aqueous solution was high, and therefore it was difficult to flow through the thin tubes in the collapsing mandrel, and the liquid feeding pressure increased, making it difficult to spray the liquid. Also, the stick strength of the finished stick is 90.
~1007, which is low and easy to break.

Using the stick-shaped casing obtained as described above, the emulsion for frankfurt sausage was filled with an automatic filling machine under the same conditions, and after passing through the steps of drying, smoking, kneading, and cooling, the contents were filled with a high-speed peeling machine. The casing was peeled off from inside.

At the time of filling, the one using release agent A provided smooth operability, but the one using release agent B caused frequent tearing and caused a great deal of trouble in operability. In addition, those using release agent C4- tended to break when attached to the filling nozzle, resulting in unsatisfactory handling, or the broken stick casing became entangled with the filling nozzle, often causing the filling operation to be stopped.

In terms of releasability by peeling and 4G, all three exhibited perfect releasability.
